Abstract

1,173,191. Glycidyl ethers. MœANYAGI PARI KUTATO INTEZET. 2 Jan., 1967 [31 Dec., 1965], No. 147/67. Heading C3B. Low M.W. polyglycidyl ethers having a viscosity not exceeding 20,000 C.P. at 20‹ C. are prepared by a two-stage condensation of a diol and an epihalohydrin in the presence of 2.35-3.95 moles of alkali per mole of diol: (1) at least 4.5 moles of epihalohydrin per mole of diol are reacted in the presence of up to 65% of the alkali to be used, after reaction excess epichlorohydrin is removed and then (2) the remainder of the alkali is added and condensation completed in the absence of any excess of epihalohydrin. The resultant resin is separated from the aqueous layer and deionized by treatment with a solvent, e.g. toluene and subsequently washed with water. In examples, bisphenol-A is condensed with 8 and 15 moles (respectively) of epichlorohydrin. A suitable alkali is NaOH which may be used as a 10-35% aqueous solution.
